Looking for insight

I'm still newer to the market, and I do own shares of AMC, GME, HYMC, and Ford. I've tried my hand at options trading, and I've been profitable on it the first go round, then lost quite a bit on the 2nd try. However, I was able to make a profit on the 3rd try which is great. I'm still learning, and it is a bit confusing at times.

Now for my questions.

1. What would be a good amount to start trading with? Would $2,000 be enough to start seeing some actual profit?
2. Should I stick to buying and holding stock, or go with options trading?
3. Which stock would you say, is the play for some serious returns?

Any and all advice is greatly appreciated. Thank you in advance!
